Accuracy of Digital Impressions for Veneer Restorations: A Narrative Review and Case Illustration

Abstract

Background: Intraoral scanners have become increasingly popular for final dental prostheses due to their precision, efficiency, and patient-friendly approach. However, their use for capturing final impressions of highly esthetic and thin restorations, such as ceramic veneers, presents unique challenges. Veneer preparations differ significantly from traditional full-coverage crowns, with their smaller and more delicate margins often located at or below the gingival level. This complexity may lead to hesitancy among clinicians regarding the routine use of intraoral scanners in such cases. Methods: A comprehensive literature review was performed to evaluate the effectiveness of intraoral scanners for final digital impressions in ceramic veneer restorations within the esthetic zone. Studies published between January 2010 and January 2025 were included in the review. Additionally, a case illustration was provided, detailing the use of an intraoral scanner to capture final impressions for a patient requiring 10 ceramic veneers in the esthetic zone. Results: The review demonstrated that intraoral scanning is a reliable technique for veneer impressions, delivering clinically acceptable outcomes. The benefits include enhanced patient comfort, improved workflow efficiency, and a reduction in chairside time. Nonetheless, clinicians must overcome a learning curve with digital technologies and ensure optimal conditions, such as maintaining a dry tooth surface during scanning. The presented case successfully illustrated the use of intraoral scanning, resulting in precise impressions and the fabrication of highly esthetic and functional veneers. Conclusions: Intraoral scanning is a predictable and effective method for capturing final impressions for veneer restorations. It offers results comparable to traditional methods while enhancing patient experience and enabling the fabrication of high-quality restorations within an efficient workflow.
